Specific implementation mode
A kind of multi-functional continuous syringe(As shown in Figure 1), logistics is put in poison through direction according to dispensing state, includes pushing away successively
Medicine metering device 10, preposition reversal valve 20 and drenching tube 30.
Graduated capacity tube 11 and piston arrangement is arranged in described push away on medicine metering device 10, in the capacity tube 11
Piston arrangement is set, handle 13 is set on the piston arrangement, the capacity tube 11 is used to control the dosage of drug,
The piston arrangement includes piston 121 and piston rod 122, handle 13 is connected on piston rod 122, handle 13 is for pushing
Piston rod 122, piston rod 122 do work for supporting piston 121, to which the liquid in capacity tube 11 is pushed out to preposition reversal valve
20。
The preposition reversal valve 20 includes preposition knob 21 and preposition spool 22, is fixedly installed on the preposition knob 21
A circle convex block 211 from high to low, the preposition spool 22 are located on convex block 211, are provided on the preposition spool 22 preposition
Two sealing rings 221, the preposition sealing ring 221 and 20 inner wall of preposition reversal valve(Such as A, B point in Fig. 2)It is bonded closed, resistance
Disconnected liquid medicine flow.
The rotation of preposition knob 21 drives convex block 211 to rotate, and 22 bottom of preposition spool is done under the conflict of convex block 211
Lower movement.
First passage 23, second channel 24 and third channel 25 are provided in the preposition reversal valve 20, described first is logical
Road 23 is connected to the capacity tube 11 for pushing away medicine metering device 10, and the second channel 24 is connected to drenching tube 30,22 He of preposition spool
It is provided with spring between third channel 25, rotates preposition knob 21 so that preposition spool 22 is against on convex block peak, foreline valve
Core 22 peaks, and spring is in compressive state, and the preposition sealing ring 221 is in A points, and liquid flows through first passage 23 and exists
Under the blocking of preposition sealing ring 221, along 22 outer wall of preposition spool, second channel 24 is flowed to(As shown in Figure 2), reach drenching tube
30.At this point, preposition reversal valve is in dispensing fill-up mode.
Rotate preposition knob 21 so that preposition spool 22 is against in convex block minimum point, and preposition spool 22 touches the bottom, bullet
Spring is in extended configuration, and preposition sealing ring 221 is in B points at this time, 221 blocking agent liquid stream of preposition sealing ring to second channel 24,
Liquid reaches third channel 25 by first passage 23 at this time(As shown in Figure 3).At this point, preposition reversal valve is in dilution mode.
The third channel 25 is connected to main body reversal valve 40, and main body knob 48 and master are provided in the main body reversal valve 40
Body spool 49 is provided with a circle convex block from high to low on the main body knob 48(Projection cube structure is as described in preposition knob 21),
The main body spool 49 is located on convex block, and there are one body seal circle 491, the body seal circles for setting on the main body spool
491 with 40 inner wall of main body switching valve(Such as C, D point in Fig. 3)It is bonded closed, blocking liquid medicine flow.The main body spool 49 and master
It is provided with spring between body reversal valve, it is logical that fourth lane 41, Five-channel 42 and the 6th are provided in the main body reversal valve 40
Road 43, the fourth lane 41 are connected to third channel 25, and the Five-channel 42 is connected with liquid storage bottle 50, the liquid storage bottle 50 with
It pushes away medicine metering device 10 to connect by channel 90, the liquid in liquid storage bottle 50 is sucked out by pushing away medicine metering device 10.
6th channel 43 is connected with vaccine bottle socket 60, and the vaccine bottle socket 60 is connected with vaccine bottle(In figure not
It identifies), the 6th channel 43 is also associated with air valve 70, and the air valve 70 includes air valve core 71, the air
It is provided with air valve spring 72 between 40 inner wall of valve core and main body reversal valve.
The liquid storage bottle 50 is connected with imbibition connector 51, and the imbibition connector 51 is connected with vaccine bottle socket 60 by sebific duct 80
It connects.Liquid storage bottle, which covers, is provided with check valve 58;
Current permutation to valve 20 be dilution mode when, rotation main body knob 48 so that it is minimum that main body spool 49 is against convex block
On point, at this point, spring is in extended configuration, body seal circle 491 is in C points, due to the blocking of body seal circle 491, liquid
Enter the 6th channel 43 by fourth lane 41, reach vaccine bottle by vaccine socket 60, liquid diluted in vaccine bottle after from
60 liquid outlet of vaccine bottle socket flows through sebific duct 80 and imbibition connector 51 enters liquid storage bottle 50, simultaneously because for just in the 6th channel 43
Normal pressure is strong, so air valve 70 is in closed state, outside air is blocked to enter the 6th channel 43(As shown in Figure 4).At this point, main
Body reversal valve 40 is dilution mode, is recycled with this so that vaccine fully dilutes.
Current permutation to valve 20 be dilution mode when, rotation main body knob 48 so that main body spool 49 is against convex block highest
On point, at this point, spring is in compressive state, body seal circle 491 is in D points, pushes away 10 handle 13 of medicine metering device, liquid
Enter from 41 inlet of fourth lane, due to the blocking of body seal circle 491, liquid flows to the 5th by 49 outer wall of main body spool
Channel 42 reaches liquid storage bottle 50, and liquid storage is discharged in air by the check valve 58 that air in liquid storage bottle 50 is covered by liquid storage bottle
Bottle 50 causes to form partial vacuum in liquid storage bottle 50.When 13 handles are pulled back, liquid is wanted in inlet capacity cylinder in liquid storage bottle 50,
Due to having partial vacuum in liquid storage bottle 50, at this point, air valve 70 is normally open, air is entered from the inlet of air valve 70
In vaccine bottle, Liquid Residue in vaccine bottle is absorbed by sebific duct in liquid storage bottle 50, to achieve the effect that absorb Liquid Residue(Such as figure
Shown in 5).At this point, main body reversal valve 40 is absorbing pattern.
The preposition reversal valve 20 includes channel 28, and 28 periphery of the channel is provided with boss 29,29 periphery of the boss
It is provided with screw thread, buckle 27, the cylinder that the buckle 27 scabbles for front-back are provided on the boss 29.
The drenching tube 30 is the bend pipe with certain camber, and card slot 38, the buckle are provided on the drenching tube 30
27 and card slot 38 adaptation form cylinder, nut 35 is provided on the drenching tube 30, the nut 35 is set in cylinder, described
Nut 35 is connected through a screw thread with boss 29 so that drenching tube 30 is fixed on preposition reversal valve 20.
The present invention by the way that preposition reversal valve 20 and main body switching valve 40 is arranged, by liquid shunting be irrigated respectively dispensing,
Imbibition, dilution mode, user can convert according to different needs, have the characteristics that one tube multipurpose, while the present invention passes through
Air valve 70 is set, syringe is sucked out in remaining liquid, realizes and is precisely administered and is lost few technique effect.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, those of ordinary skill in the art are to this hair
Other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,
It should all cover in scope of the presently claimed invention.
